摘要
随着环境问题的日益突出和能源短缺越来越严重,煤化工企业的污水处理成为城市整治的重点,所以煤化工企业必须要优化废水排放技术,解决其耗水量、废水排放量大、污染物浓度含量高的问题。在这样的背景下,新型煤化工废水零排放技术得以发展,实现"无废水外排"。其技术工艺复杂,需要通过多道工艺处理来实现煤化工废水的"零排放",这对于解决我国水资源短缺和环境污染有重要的作用,是煤化工产业可持续发展的要求。
With the increasingly prominent environmental problems and the increasingly serious energy shortage,the sewage treatment of coal chemical enterprises has become the focus of urban rectification.Therefore,coal chemical enterprises must optimize wastewater discharge technology to solve their water consumption and wastewater discharge.The problem of high concentration of pollutants.Under such a background,the new coal chemical wastewater zero-emission technology has been developed to achieve“no wastewater efflux”.The technical process is complex and requires multiple processes to achieve“zero emissions”of coal chemical wastewater.This has an important role in solving China's water shortage and environmental pollution,and is a requirement for the sustainable development of the coal chemical industry.
